A striking, showy, old-time slab of lustrous, massive, native copper in porphyritic rhyolite from the lesser-known Kingston Lode of Michigan Copper Country. The slab comes with two old labels, including one affixed to the back of the slab. The exhibit face has been sprayed with lacquer to improve presentation, which is nomal for polished specimens of this type. Ex Richard Hauck Collection. Kingston lode copper in "jasper" is not true jasper, but in actuality is a porphyritic rhyolite (check through Marc Wilson in Min Rec Special Edition). 7.4 x 6.0 x 0.9 cm
